At its heart, a Caucasian is a creamy, dreamy cocktail. It’s simply vodka, coffee liqueur (like Kahlúa), and a splash of heavy cream or milk. Think of it as a grown-up iced coffee that wears a party hat.
You might know it by its far more famous name: the White Russian. The term "Caucasian" just popped up as a fun, quirky nickname, famously used by The Dude in the movie The Big Lebowski.
So when Jeff Bridges' character, The Dude, shuffles into a bowling alley bar and orders a "Caucasian," he's really asking for a White Russian. It’s a name that sounds fancy but tastes like comfort.
